Adding 3′ terminus nucleotide modification increases the specificity of the assay at high PCR cycles. (A) Amplification results using inner primer with different 3′ terminus nucleotide modifications at 40 PCR cycles. (B) Amplification results from BRMs and processed materials using inner primer with both 5′ terminus and 3′ terminus modifications at 40 PCR cycles.
